Ha ha ha ha ha ha -- Great one, tutuf ! All the 3-D glasses I own have a blue gel lens and a red gel lens. So I prefer a color change from green lens to blue lens. Since Threadless allows 5 ink colors your design can go on any colored shirt. My favorite t-shirt color would be a light colored one like pastel yellow or natural ( dark colored shirts would lose the tiny details of the monster's few loose hairs, and bright colored shirts would compete with the lens of the glasses).
